BNX® 1425 is a multifunctional additive that functions as an antioxidant for the stabilization of plastics, synthetic fibers, elastomers, and rosin ester tackifier resins. The product is also an effective esterification catalyst that is particularly useful in the production of rosin esters and in the solid-state polymerization of PET and other thermoplastic polyesters.

Applications:
BNX® 1425 is particularly useful as a stabilizer and esterification catalyst in rosin esters and in PET and other thermoplastic polyesters. It is also effective for the stabilization of polyolefins (particularly polypropylene fibers), cross-linked elastomers, and specialty adhesives.

Advantages:

• In the production of rosin esters, BNX® 1425 enables shorter reaction times and gives products characterized by reduced discoloration, a low acid number, and improved heat stability.

• In PET, BNX® 1425 provides faster solid-state polymerization, improved color, and reduced generation of acetaldehyde.

• Non-discoloring

• Excellent resistance to migration and extraction

• Low-volatility during polycondensation and high temperature processing
